About Plasma (The energy of the 21st century)

Ice melts and returns to the state of water, water evaporates and turns into water vapour. This pattern of transition between the three material states of solid, liquid and gas is familiar but there is actually another fourth material state. This fourth material state is called “plasma”.
As energy is applied the electrons of a material the orbits of these electrons widen, this process is called “excitation”. Electrons that escape are called “free electrons”, and the remaining particles are known as “ions”. In this state with electrons flying around and ions dancing around the bond between electron and nulceus is unstable, this state of chaos is called “plasma”.

The Northern Lights, or aurora, are caused by the energy in radioactive rays from the sun (solar wind) colliding with electrons in oxygen and nitrogen in the atmosphere. Free electrons that result from these collisions are then deflected by the earth’s magnetic field to create a plasma effect.
For an example coser to home, fluorescent strip lights and neon signs employ a “glow discharge plasma”. Other examples include high temperature plasma where electrons and ions are completely dissociated as used in material processing. Plasma torches, known as “plasma jets” or “arc plasma” are being widely used in the fields of metal refining and fusion.
Currently plasma technology is most being widely used in the field of semi-conductor manufacturing, in particular deposition, etching and ashing process applications. Plasma technology is also vital to the production of DVD, “opto-magnetic disks” and electronic components that support the IT industry. New emerginging applications include gas scrubbing of ecologically harmful gases and film coatings to prevent leakage of environmental toxins from plastic food and beverage containers.

We can truthfully say that the 21st century is an era when “plasma” will influence our daily lives. At ADTEC Plasma Technology, we are striving to develop the plasma generators that form the source of plasma energy to meet the needs of the wide range of fields that utilize plasma.
